COELLO HAMILTON, OF PLYMOUTH, MICHIGAN.

RIFLE.

To all whom "it may concern:

Be it known that I, CoELLo HAMILTON, citizen of the United States, residing at Plymouth, county of lVayne, State of Michigan, have invented a certain new and useful Improvement in Rifles, and declare the fol lowing to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in rifles, shown in the accompanying drawings and more particularly pointed out in the following specification and claims.

The object of my invention is an improvement in the general construction by which the assembling of the parts is simplified and the cost of manufacture materially reduced.

One of the features of the invention consists in the means employed for locking the barrel and stock in position for firing.

Another feature is the means employed for actuating the shell extractor operated by unlocking or breaking the barrel and stock.

Another feature is the means employed for securing the trigger guard to the frame.

Another feature is the employment of a single spring to control both the hammer and barrel locking mechanism.

Another feature of the invention consists in providing means whereby the cartridge cannot be fired if the barrel is not in locked relation with the stock.-

Other advantages and improvements will hereafter appear.

In the drawings accompanying this specification: Figure 1 is a'side elevation of the rifle. Fig. 2 is a side elevation of a portion of the rifle with one of the receiving brackets removed to show the firing mechanism, the barrel being in locked position. Fig. 3 is a similar view partially in section, showing the parts underlying the wall of the brackets in the position indicated in Fig.

against firing the cartridge when in this position. Fig. 6 is a view with the parts in similar position to that shown in Fig. 5, the barrel being partially in section and onehalf of the depending bracket of the barrel removed to show the operation of the extractor mechanism. Fig. 7 is a fragmentary plan view showing the manner of engaging the receiver bracket of the rifle barrel to the stock. Fig. 8 is a similar fragmentary view with parts in section to more clearly disclose the means employed to secure the receiver bracket to the stock. Fig. 9 is a cross-sectional view through the stock on line 99 of Fig. 8. Fig. 10 is a fragmentary view of one of the outer shells of the rifle barrel showing the slotted depending wall and platform upon which the extractor is supported. Fig. 11 is a cross-sectional view on line l111 of Fig. 10. Fig. 12 is a longi tudinal section through a fragment of the outer shell of the barrel showing the de pending bracket. Fig. 13 is an end elevation of the same. Fig. 14 is a perspective view of the lever controlling the operation of the extractor,the view also shows the extractor connected therewith. Fig. 15 is a perspective view of the trigger guard. Fig. 16 is a sectional view of one of the assembling nuts and screws serving as pivots for the firing mechanism and for engaging the walls of the receiver brackets together.

Referring now to the letters of reference placed upon the drawings :A indicates the stock. B the barrel preferably composed of a plurality of concentric tubes,the outer one being provided with a depending bracket B beneath the breech end B O are receiver brackets struck up of sheet metal and formed in two parts embracing the depending bracket of the barrel, the lat ter being pivoted thereto by the screw and nut c. The opposing walls of the receiver brackets are secured together by like assembling nuts and screws 0 which also serve as pivots for the firing mechanism.

D is the hammer pivoted at d between the walls of the receiver bracket.

E is a lever to control the locking of the rifle barrel in position for firing, and also the operation of the link F for actuating the eXtractorG. The lever E is constructed of sheet metal and fulcrumed upon the hammer pivot cZ,its free end being formed with a thumb piece 6 for convenience in operating it. The pivotal end of the lever is shaped to form a link E pierced to receive a bolt 7 connecting the link Fv thereto. The link F is also constructed of sheet metal and is slotted at its forward end as indicated at f,

for the passage of the pivotal nut and screw 0 engaging the walls of the depending rel, having a ledge h adapted to partially support the extractor G. The extractor G is prbvided with a projecting transverse pin 9 secured thereto which on one side extends through the slot in the depending wall H of the barrel. Projecting upwardly from the link F are fingers f spaced apart as indicated in Fig. 14 to receive between them the depending wall H and the end of the extractor G, being adapted, however, to encounter the projecting ends of the pin 9 whereby the extractor is actuated.

f is a depending lug formed integral with the link and pierced to receive the main spring pin 1 which is free to move through said aperture. The rear end of said pin is enlarged as indicated at I and pointed to enter a suitable depression formed in the lower end of the hammer D.

I is a main spring supported on said pin.

J is the trigger pivoted upon the screw J between'the rip-standing ears K of the trigger guard K. The forwardend of the trigger guard is notched as indicated at in Fig. 15, to receive the projecting wall of the abutting receiver brackets C, by which means this end of the guard is secured against displacement ;--the trigger pivot J extending through the abutting walls of the receiver brackets G and the guard K secures the opposite end of the latter against displacement.

Between the ears K of the trigger guard and formed integral with the guard, is a projecting portion is bent back upon itself to receive the end of a coil spring L, adapted to bear against the trigger to hold it in locked relation with the hammer.

As indicated in Fig. 7, the receiver brackets C at the point C are formed narrower relatively than between the portion housing the trigger mechanism, whereby a narrower and thereby neater formation at the grip stock is possible.

A is a lining in the kerf A formed in the end of the stock and shaped to receive the ends of the receiver brackets. A is a screw securing said lining to the stock, provided with a relatively large head tapering at its forward end as indicated at a. As shown in cross-section in Fig. 9, the walls of the receiver bracket are given an arc-shaped formation indicated at C to receive the head of the screw A which upon entering between the spaced walls of the bracket ex' pands them slightly laterally. The lining A is also provided with a complementary arc-shaped formation to receive the round or, convex portion of the receiver bracket. It will now be noted that upon forcing the receiver bracket into the kerf formed in the end of the stock that the head of the screw will enter between the opposing walls of the receiver bracket causing them to expand, thereby engaging the lining A in the kerf of the stock and thus assist in securing the barrel to the stock. The relatively long convex portion also serves to prevent any tendency of the receiver bracket to rock on the bolt M by means of which the bracket is secured to the stock. The removable bolt M is provided with a suitable milled head at one end for facility in operating it,the other end being screw-threaded to engage the counter-sunk nut m. The opposite side of the stock is provided with a counter-sunk washer m to provide against the wear incident to the entry and removal of the bolt.

Having thus indicated the several par-ts by reference letters, the operation of the invention will be readily understood. When it is desired to release the locking mechanism for the purpose of inserting a cartridge and to eject the old shell, the lever E is operated by pressing upon its thumb piece; the pin 7" may thus be forced out of locked relation with the notched end of the arcshaped depending bracket and the fingers f of the link F drawn toward the projecting pin of the extractor. The adjustment of the parts is such that upon the fingers of the link coming into contact with the projecting pin of the extractor, the locking pin of the lever is released from the notch of the bracket as clearly indicated in Fig. 4; of the drawings. The barrel portion may now be broken from the stock by forcing it to turn on the pivot c. This action causes the arc-shaped portion of the bracket to pass in front of the locking pin thereby forcing the link F to the limit of its movement, at the same time the projecting pin 9 of the extractor is brought into operating contact with the up-standing fingers of the link F;this action pushes the extractor rearward discharging the shell. A cartridge may now be inserted and the bar-rel portion swung back upon its pivot into firing position.

Immediately upon the locking pin returning to the notched portion of the bracket, 'the spring I becomes active forcing the link F forward to its normal position and the locking pin into the notch, again securing the barrel and stock portion in firing relation. In returning the parts to their locked or normal position, the end 0 of the abutting wall of the receiver bracket forces the extractor forward to its initial position.

As indicated in the description of the parts, the receiver bracket and stock may be readily disconnected by releasing the bolt M engaging the receiver bracket and stock.

Having thus described my invention, what I claim is:
